Definitions

  • the present invention is generally concerned with clutch release bearings and more particularly with those for equipping automobile vehicles.
  • a clutch release bearing generally comprises an operating element which is adapted to be operated on directly or indirectly by a control member, in practice a clutch release yoke, a drive element adapted to operate on the clutch release device of a clutch and bearing axially on the operating element, directly or indirectly, and coupling means which couple said drive element axially to said operating element.
  • the present invention is more particularly directed to the implementation of these coupling means.
  • the object of the present invention is a clutch release bearing, in particular for automobile vehicles, of the kind comprising an operating element adapted to be operated on directly or indirectly by a control member, in practice a clutch release yoke, a drive element adapted to operate on the clutch release device of a clutch and bearing axially on the operating element, directly or indirectly, and coupling means which couple said drive element axially to said operating element,
  • this clutch release bearing being characterized in that said coupling means are in one piece with a substantially plane plate of overall U-shaped configuration with two arms which are generally parallel to each other joined together by a curved middle part in the shape of an arch, which constitute two clips disposed at generally diametrally opposite positions relative to each other and which each originate from a respective arm of said plate, the whole constituting a single part.
  • the plate of which the coupling means form part may advantageously be fitted by simple radial engagement over the operating element.
  • the bearing plate When as is usually the case, and especially in the case where it is made of a synthetic material, there is associated with the operating element an anti-wear plate, usually called the bearing plate, which bears axially against it, either directly or indirectly, the plate with which, in accordance with the invention, the clips constituting the coupling means are in one piece may advantageously, if required, and in accordance with a first development of the invention, itself form a bearing plate of this kind.
  • a single coupling and bearing member being thus used to constitute the bearing plate and the coupling means, the clutch release bearing in accordance with the invention advantageously comprises only a minimum number of component parts, so that its fabrication and assembly are advantageously and economically simplified.
  • the plate with which, in accordance with the invention, the clips constituting the coupling means are in one piece may be part of a coupling member separate from the bearing plate.
  • the clips constituting the associated coupling means must conjointly and preferably be made of relatively thin sheet metal, since it is desirable for them to feature some elasticity, for assembly purposes.
  • the coupling plate is directly superposed on the bearing plate.
  • each clip constituting the coupling means are preferably offset relative to each other not only axially but also radially, that through which a clip of this kind connects to the coupling plate being generally further from the axis of the assembly than the other.
  • the fingers of the control member are therefore given sufficient access to the arms of the bearing plate, the disengagement of the fingers being facilitated at the same time as achieving appropriate fabrication and installation of the coupling means to be employed.
  • the elasticity of the coupling means is favored.
  • FIG. 1 is a side view of the clutch release bearing in accordance with the invention in the direction of the arrow I in FIG. 2;
  • FIG. 2 is a rear view of it as seen in elevation in the direction of the arrow II in FIG. 1;

  • FIG. 15 is a perspective view of the bearing and coupling plates that the clutch release bearing in accordance with the invention comprises in this embodiment.
  • the clutch release bearing comprises an operating element 10 which is adapted to be operated on by a control member, in practice a clutch release yoke 60 schematically shown in dashed outline in FIGS. 12 and 13, in practice through the intermediary of a bearing plate 11 which bears axially against it, a drive element 12 adapted to operate on the clutch release device of a clutch, also not shown, and also bearing axially on the operating element, and coupling means to be described in detail hereinafter which axially couple said drive element 12 to said operating element 10.
  • the operating element 10 comprises an axial sleeve 13 through which it is adapted to be slidably engaged on any form of support and guide member, not shown, for example the flared guide tube usually surrounding the input shaft of the associated gearbox, and a transverse flange 14 on which the drive element 12 bears axially.
  • the sleeve 13 and the flange 14 are in one piece.
  • the drive element 12 consists of a ball bearing.
  • the drive element 12 features at the corresponding end of its inner race 16 and in one piece therewith an annular radial flange 18 directed radially away from the axis of the assembly.
  • this radial flange 18 forms two lateral arms 19 at positions that are generally diametrally opposed to each other.
  • each is that of an isosceles trapezoid, the longer parallel side joining it to the radial flange 18.
  • the overall shape of the radial flange 18 is that of an olive with the ends cut off and in practice the flange 14 of the operating element 10 has a similar contour with its curved parts slightly spaced from that of the radial flange 18.
  • the operating element 10 preferably features at least one lug 20 projecting axially from the periphery of its transverse flange 14.
  • the lug 20 extends over part only of this edge, from the straight edge forming the shorter parallel side of the arm 19 concerned and along only one of the oblique sides thereof.
  • the drive element 12 which is thus in contact with the flange 14 of the operating element 10 through the radial flange 18 of its inner race 16 is mounted to be movable in all transverse directions relative to the operating element 10, within predetermined limits of radial displacement, naturally.
  • FIG. 3 there is some clearance between the axial part of the inner race 16 of the drive element 12 and a boss 22 in line therewith on the operating element 10 at the point where its axial sleeve 13 merges with its transverse flange 14.
  • the lugs 20 that the operating element 10 features are both on the same side of the axial plane of the assembly passing through the middle section of the arms 19 of the drive element 12.
  • the bearing plate 11 is on the opposite side of the flange 14 of the operating element 10 to the drive element 12.
  • the bearing plate 11 in practice bears directly in the axial direction against the corresponding side of the flange 14 of the oerating element 10, without any other member being disposed between them.
  • the coupling means that axially couple the drive element 12 to the operating element 10 are in one piece with a plate which, in the embodiments shown in FIGS. 1 through 11, is the bearing plate 11, the whole forming part of a single member 23 referred to hereinafter for simplicity only as the coupling and bearing member; as will be described in detail hereinafter, the coupling means consist of two clips 29.
  • the coupling and bearing member 23 is shown in isolation in FIG. 6.
  • the bearing plate 11 that it forms is in practice substantially plane and of generally U-shaped configuration, with two generally parallel arms 24 and a curved middle part 25 in the shape of an arch joining the arms 24 together.
  • the width of the main part of the arms 24 is greater than that of the curved middle part 25 and at least their respective edges facing each other are parallel to each other and respectively cooperate for purposes of angular immobilization with two radially projecting bosses 47 each with a plane facet 26 provided for this purpose, as well as for guiding the associated control member and immobilizing the clutch release bearing against rotation thereon, in generally diametrally opposite positions on the axial sleeve 13 of the operating element 10, on the same side of the flange 14 of the latter as the bearing plate 11.
  • the rib 27 that the operating element 10 thus features is disposed at a position which is generally diametrally opposite the lugs 20; this may facilitate its fabrication.
  • the coupling means which axially couple the drive element 12 to the operating element 10 comprise two clips 29.
  • each of the two clips 29 originates from the respective arm of the bearing plate 11.
  • the two clips 29 are generally parallel to each other and each originates from the part of the arm 24 of the bearing plate 11 projecting beyond the curved middle part 25 thereof, being continuous with the thus projecting part of the arm 24.
  • Each of the two clips 29 is of generally U-shaped configuration with one branch 30 formed at least in part, or even virtually totally, by the arm 24 of the bearing plate 11 from which it originates, more precisely the projecting part of this arm 24; the other branch 31 forms a return which is generally parallel to the arm 24, being joined to the other branch by a curved middle part 32.
  • the clips 29 that the coupling and bearing member 23 thus features in accordance with the invention are hooked, that is to say radially engaged in the manner of a staple, onto the assembly consisting of the transverse flange 14 of the operating element and the radial flange 18 of the drive element 12, in line with the lateral arms 19 of the latter, as shown in the case of one of them in FIG. 5.
  • the drive element 12 has also to be operated on by axially acting elastic means adapted to urge it towards the operating element 10.
  • these axially acting elastic means are also in one piece with the bearing plate 11, like it and like the clips 29 constituting the aforementioned coupling means forming part of the coupling and bearing member 23.
  • the axially acting elastic means are formed by the clips 29 themselves, the branch 31 thereof which forms a return being to this end and as shown shaped so as to be elastically deformable, in cooperation with the curved middle part 32 which joins it to the other branch 30.
  • each clip 29 is generally rounded (part cylindrical), with its concave side facing away from said arm 19 and, beginning from this end, said branch 31 diverges from the other to the point where it merges continuously with the corresponding curved middle part 32.
  • the branch 31 of the clips 29 is advantageously relatively long and therefore highly resilient, which provides for optimum accommodation of any manufacturing tolerances, the influence of these on the corresponding elastic force being thus minimized.
  • two right-angle fingers 34 are provided which, in this embodiment, are in one piece with the flange 14 of the operating element 10. Each is in line with a respective arm 24 of the bearing plate 11.
  • these right-angle fingers 34 is preferably exploited by forming at their root, in the vicinity of the corresponding plane facet 26 of the sleeve 13, a pocket 35 into which the end of the corresponding arm 24 of the bearing plate 11 is inserted for improved radial retention and to contribute to its axial retention.
  • the coupling and bearing plate 23 in accordance with the invention has to be fitted at a slight slant.
  • the clips 29 are generally aligned with each other, being oriented in opposite directions relative to each other.
  • the inner race 16 and outer race 17 of the drive element 12 are castings instead of being fabricated from sheet metal and it is through its outer race 17, more precisely the corresponding edge thereof, that the drive element 12 bears axially against the transverse flange 14 of the operating element 10.
  • each clip 29 bears directly on the other edge of the outer race 17.
  • the right-angle fingers 34 procuring axial retention of the clutch release bearing relative to its control member are in one piece with the bearing plate 11, like it and like the clips 29 forming part of the coupling and bearing member 23.
  • each arm 24 of the bearing plate 11 is formed by bending to U-shape an extension of each arm 24 of the bearing plate 11, this extension being bracketed at its root by two slots 37 separating it from the remainder of the end of the arm 24 from which it is formed in this way.
  • edges of the arms 24 of the bearing plate 11 which face each other may each be bordered by a right-angle lip in one piece therewith for guiding the associated control member and immobilizing the clutch release bearing from rotating thereon.
  • pockets 35 may be provided on the operating element 10 for the ends of the arms 24 of the bearing plate 11 to be inserted in, said pockets 35 being formed, for example, by hooks in one piece with the transverse flange 14 of the operating element 10 and bracketing the right-angle fingers 34 formed by the bearing plate 11.
  • the plate 11 with which the clips 29 forming the coupling means which axially couple the drive element 12 to the operating element 10 are in one piece itself forms the bearing plate.
  • this bearing plate 11 comprises a circumferentially continuous annular washer 44 around the axis of the assembly by which it is adapted to be engaged over the sleeve 13 of the operating element 10 and, in diametrally opposed positions relative to each other, two arms 46 in one piece with the washer 44 and extending generally radially relative thereto, for the fingers 45 of the clutch release yoke constituting the control member 60 to bear on.
